Which statements correspond to amphibolic pathways? 1. anabolic and catabolic reactions are joined through common intermediate 2. shared metabolic pathways 3. feedback inhibition can regulate rates of reactions 4. both types of reactions are necessary but do not occur simultaneously
THIS IS THE BEST ANSWER 👇
1. Anabolic and catabolic reactions are mediated by an intermediate
For example, the krebs cycle is an amphibious pathway.
In the krebs cycle you can see an anabolic reaction: the combination of acetyl-coa and oxalacetate to obtain citrate; subsequently some catabolic reacts when citrate (with 6 carbon atoms) loses its carbon to regain oxalacetate (with 4 carbon atoms).
